でcpanを構成してo conf initいるときに：次のエラーが表示されます：

If you're accessing the net via proxies, you can specify them in the
CPAN configuration or via environment variables. The variable in
the $CPAN::Config takes precedence.

Your ftp_proxy? [n]
Your http_proxy? [n]
Your no_proxy?

If your proxy is an authenticating proxy, you can store your username
permanently. If you do not want that, just press RETURN. You will then
be asked for your username in every future session.

Your proxy user id?

Can't access URL ftp://ftp.oss.eznetsols.org/cpan/MIRRORED.BY.

Please check, if the URLs I found in your configuration file
(ftp://ftp.oss.eznetsols.org/cpan/) are valid. The urllist can be edited.
E.g. with 'o conf urllist push ftp://myurl/'

Could not fetch MIRRORED.BY

プロキシの問題のようです。

次のことを試しましたが、成功しませんでした。

  1. 【動作確認済みping】
  2. /etc/resolve.confエントリ： nameserver my IP address
  3. プロキシサーバーを追加してみました： o conf http_proxy http://proxy.mycorp.com:8080/

教えてください、これに対処する方法。ありがとう。

CPANは（非効率的に）FTPサーバーがダウンしているように見えると言っています。

$ wget ftp://ftp.oss.eznetsols.org
--2013-02-03 20:51:09--  ftp://ftp.oss.eznetsols.org/
           => ‘.listing’
Resolving ftp.oss.eznetsols.org (ftp.oss.eznetsols.org)... 111.90.255.253
Connecting to ftp.oss.eznetsols.org (ftp.oss.eznetsols.org)|111.90.255.253|:21... failed: Connection refused.

そのFTPサーバーはCPANミラーのリストに存在しませんが、ミラーリストは古くなっています。

別のCPANミラーを試してください。o conf urllist shift http://cpan.pair.com/例えば。
